NER Low roofed carriages

I've been very quite since Christmas and haven't posted much, a combination of family duties, retirement time filled with things you never dream of and a list of household decorating requirements from erindors.

In the few hours of piece and quite I have been looking around for something a bit bigger and more complex and found a brilliant article in the NER Express on low roofed carriages and their use in making up comp B sets. Additionally I located a drawing of some low roofed stock, a bit basic but sufficiently detailed to make a start. Comp B sets were basically a 1st/3rd composite booked end by a pair of brake thirds, occasionally strengthened by a second composite. These sets seem to have been used from their inception in the early 1900's and were still in use long into BR days.

Having read and reread the article a number of times, what what glaringly obvious was the standardised nature of all the diagrams, every 3rd and 1st compartment had the same dimensions, only the brake compartments varied depending on how many 3rd's were used three, four and occasionally five, so I wondered if a single Fusion 360 project could cover any diagram I chose to model, so I gave it a try and rapidly fused my brain stopped and had a rethink.

The plan was to initially model a Dgm 53 brake third, G3333 and a Dgm 64 3rd/1st composite, 3311133. The second brake third may be another Dgm 53 but more likely will be a Dgm 104, G33333, these had side lookouts rather than clerestory lookout so would give a bit of variety.

Anyway on to where I am up to.

 

The project so far and I have admit there's no logic to it, it's been done on a pick and mix basis.

Having abandoned the one project philosophy, I initially went for separate projects for the roofs, bodies and underframe which caused more brain meltdown. That also got scrapped, so it's currently 6 projects, one to cover the interior parts, common to all (which should have included the common lamp components but didn't), separate roofs, separate bodies and another to cover the common 49ft underframe.

Dgm 53 Brake / Third

First up the roof, the passenger end was relatively easy, the guards end a fair bit more taxing, especially the gas supply pipe run.



Then end to roof supply was a $%^$$£" and I am still not happy with it, but it is what it is for now with the first of the lamps positioned:



The end of the pipe supply was much easier:




The body was relatively simple once I had figured out that 4 3rd class 5ft 11" long and and a 24ft 4 1/2" guards compartment don't add up to 343mm long (in 7mm), but by portioning out the missing length to account for the ends and partitions, it all added up.

 

The Dgm 64 Composite

This isn't as far advanced.

The roof was drawn based on my experience with the the Dgm 53 roof and using most of its components:



The gas supply end again drawn with the Dgm 53 just lacks the windows, while the emergency brake end is identical.





A commercial Westinghouse pipe and hose will be added.

I'm currently drawing up the body side which should be relatively simple.

 

Finally (for now) the interior.

The seating and the lighting units were drawn using a very detailed drawing of a Dgm 5 Clerestory carriage that I have. The low roof stock drawing didn't include these.
One naughty thought I had was the netting for the overhead storage could be snipped from a pair of the bosses fishnets, sadly a) I wouldn't dare and b) she doesn't have any.
It looks like I may need to buy some.

3rd/3rd and 3rd first seating:



And as looney tunes would say thats all for now folks!

 

Thanks for the suggestions Rob, when I get around to it I will do some digging, but not as much fun as fish net stockings,

 

Paul,
Better threaded through the luggage brackets than treaded through my fishnets!

But a very good idea.

 

Boringly mundane, but the Dgm 64 Side proved to be as straight forward as I thought.



Since I have no domestic duties for the rest of the day (unless she thinks differently), next is the chassis which is common to all the low roof stock.

Being on a roll I decided to mock up a Dgm 104 body, sadly I haven't been able to find a diagram of on, so this is interpolated based on a drawing of Dgm 53 with side duckets that I have (a few later builds had duckets rather than clerestories). The Dgm 53 shows the ducket immediately next to the last 3rd, then a 2 panel section before twin doors, so I copied that logic. The second pair of doors were omitted as if I included them there would have been more door than side!



The next challenge is the low roofed drawings I have don't shown the stricture of the chassis. I have a very detailed drawing of the 52ft chassis, which I plan editing down to represent the 49ft chassis, then I can make a start on the chassis details. The boss is out all day so I may well be able to make some progress on it.

 

Hi Paul,

That was my original plan and is sort of how I have done it now. I have side sections for each of the 3rd and 1st class compartments, with separate sections for the two guards sections. All I need to do to create a side is plug together the relevant sections and hey ho I have a side. The roofs are not set up as modules they have been draw as a single section. Even with a mono x the coaches would need chopping into sections to fit the build plate. I suspect the roofs will need 3 sections to enable 45-45 degree printing, but that's a battle to come.

As for the kettle, it's barely ever off I am a serious tea addict. so the warming brew is an easy job, She's off leading a 12 mike walk with some of our climbing club members so wont be back until after dark which gives me plenty of "free time" to play.

 

Spent some of yesterday vegetating with daytime tv (sad I know) before making a start on the underframe based on the 52ft underframe. Later today or more likely tomorrow I will add the westie brake, reserve air reservoir and pipe work along with the gas cylinders and piping. As for welcoming tea, I was literally in the middle of making a brew as she walked in, pure class timing.

I will have you know I have excellent legs and I think they would look good in fishnets, perhaps

 

Well the older moss (herindoors) and the youngest (my little princess 3 year old this week) have spent the last hour "baking" so I have had some fiddling time.

So The brake gear et al:



We are off to the playground soon so the gas cylinders and pipes will have to wait.

 

A few bits more added to the chassis, upper and lower footboards and queen posts. All that is left to do is the turnbuckle and the gas supply both will definitely be adlibbed as they aren't shown on any drawings I have. Then onto the fox bogies.

 

Hi Paul

Will have a look at your suggestions, but, yes always planed printing it parallel to the build plate. Haven't decided how to chop it up the fit yet. same with the body and roof, my thoughts were to make sure each component was chopped at a different point, so as to not create one line of weakness through the chassis, body and roof, but all that's for later now.

Hi Rob,

I don't think an etch scan will help much, the etch is what it is I am concentrating of the spring, axle box and bolster details so I can dress up a limited etch. That massive file of photos you sent me are a great help its just a pity the photographer didn't account for parallax, but used in conjunction with the Kemilway diagram I am making serious progress with the spring assembly. Since all three of the women are off on a shopping trip I have plenty of playtime until they get back so there should be something to look at later on today.
